Just because >IPv6 provides boatloads more space doesn't mean that I like wasting >addresses :) Another side of that argument is operational complexity ... /126's do make the addresses harder (as a previous poster mentioned) as well as inducing other potential headaches (reserved address to watch out for, requiring another route to get to a client's network, etc). That is why the official answer is to always use /64s, even on PtP links. This is one area where the real world and the IETF don't always agree, and in this case that can be OK. > >jms /TJ
